Vesico-Ureteral Reflux*

Toxic epidermal necrolysis (T~EN) is a severe mucocutaneous disease characterized by epidermal necrosis possibly extended to the entire body surface and involving multiple internal organs. Digestive tract may be involved too, but there is few report about gastrointestinal lesion in patient with TEN. Recently we experienced a case of TEN with gastrointestinal bleeding in previously healthy 32-year-old woman. The condition developed three days after the initiation of treatment with NSAID and progressed caudally, involving 60 percent of the skin surfaces. During a period of admission gastrointestinal bleeding was noticed. The gastrofiberscopy showed diffuse superficial mucosal lesion with oozing from swollen friable and erythematous mucosa. The skin lesion was progressed inspite of withdrawal of causative agents. The patient was expired due to combined septic shock 10 days later. We report this case with gastrofiberscopic findings and a brief review of literature.

A case of infectious mononucleosis was presented. She was admitted to the hospital with the anterior cervical lymphadenopathy. Erythematous skin rashes on both low extermities, and splenomegaly. Her chief complaints were fever and sore throat. She showed atypical lymphocytes in peripheral blood smear with relative lymphocytosis. Mono-spot test was positive. She received symptomatic therapy and discharged without any complications. So, we report this case and review the brief literatures of infectious mononucleosis with the respect to etiology, clinical course, and histological characteristics of the disease.

PURPOSE: This study was performed in order to compare unenhanced CT with diffusion-weighted, T2-weight-ed,and fast FLAIR MR imaging in the detection of hyperacute cerebral ischema induced in a dog and to deter-mine whichmodality first detected cerebral ischemia. MATERIALS AND METHODS: Experimental cerebral infarction was induced bythe occlusion of intracerebral arter-ies using embolic materials (polyvinyl-alcohol, 300 -6 00 micro) introducedthrough a microcatheter into the internal carotid artery of five dogs weighing 12 -20 kg. Serial CT and MR imageswere obtained at one hour intervals from one to five hours after occlusion, and were analyzed independently by tworadiologists. We assessed changes in attenuation, as seen on unenhanced CT and the signal intensity of the lesionon each MR image, and measured the contrast-to-noise ratio (CNR) of the lesions. RESULTS: Ischemic lesions weredetected on unenhanced CT 1 -3 hours after occlusion of cerebral arteries. In all dogs, the lesions were detectedearliest on diffusion-weighted images obtained at 1 hour. They were detect-ed on T2-weighted images at 3 -5 hoursand on fast FLAIR images of 2 -5 hours. The CNR of ischemic lesions increased gradually during the 5-hour period.It was highest on diffusion-weighted images, while on unen-hanced CT, T2-weighted, and fast FLAIR images it wassimilar. CONCLUSION: Hyperacute ischemic lesions were detected earliest on diffusion-weighted images, and earlieron unenhanced CT than on fast FLAIR or T2-weighted MR image.

PURPOSE: The purpose of this study was to analyze the clinical effectiveness of open reduction in the treatment of distal humeral fracture using a newly designed combined approach of anterolateral and lateral approaches to protect the radial nerve. MATERIALS AND METHODS: We investigated 24 consecutive cases of distal humeral fracture who received open reduction and internal fixation with a plate and screws with a minimum follow-up period of 1 year. We analyzed the patients' age, sex, fracture pattern, timing of the union, range of motion of the elbow joint, and complications. The Mayo elbow performance index (MEPI) was employed for the assessment of elbow joint function. RESULTS: Clinical union was observed at 10.8 weeks (6~20 weeks) on average. Pre-operatively, there were 3 cases of incomplete radial nerve palsy. All of the cases recovered, and there was no additional radial nerve palsy due to surgery. According to the MEPI, 13 cases were "excellent" and 10 cases were "good" or better, comprising 95.83% of the cases. The range of motion at the elbow was 5.5 degrees (0~15 degrees) of extension, and 131.5 degrees (120~145 degrees) of flexion, suggesting no functional disability. The duration of return to work was 11.2 weeks (5~32 weeks) on average. There were no nonunion, malunion, or infection complications. CONCLUSION: The combined anterolateral and lateral approach we designed is a clinically effective approach due to facilitation of protection of the radial nerve and attainment of adequate fixation space.

Mechanical complications of acute myocardial infarction which may lead to heart failure or shock include ruptute of left ventricular free wall, ventricular septum and papillary muscle. The clinical characteristics of these lesions vary conservative management alone has high mortality rate, for which reason surgical repair of these defects are essential. Structural defects including rupture of the left ventricular free wall, ventricular septum, and papillary muscle, accout for 5% to 20% of all deaths from acute myocardial infarction. Among these, ventricular septal defects occur in approximately 1% of all myocardial infarction, and account for up to 2% of deaths subsequent to myocardial infarction. Rupture of the ventricular septum following acute myocardial infarction(AMI) is associated with high mortality rate, as 54% of the patients succumb within two weeks, 87% within two months and 92.5% during the first year. We experienced two cases of postinfarct ventricular septal defects(VSD) which had been repaired within 1 week after AMI due to progressive deterioration of patients` conditions, and were to be reoperated because of repeated septal ruptures in postoperation period and development of cardiogenic shock.

PURPOSE: The aim of this study was to characterize Korean patients with Fanconi anemia (FA), which is a rare but very challenging genetic disease. METHODS: The medical records of 12 FA patients diagnosed at Chonnam National University Hospital from 1991 to 2012 were retrospectively reviewed. RESULTS: The median age at diagnosis was 6.2 years. All patients showed evidence of marrow failure and one or more physical stigmata. Chromosome breakage tests were positive in 9 out of 11 available patients. The median follow-up duration was 69.5 months. The Kaplan-Meier (KM) survival of all patients was 83.3% at 10 years and 34.7% at 20 years, respectively. Seven patients underwent 9 stem cell transplantations (SCTs). Among them, 5 were alive by the end of the study. Ten-year KM survival after SCT was 71.4% with a median follow-up of 3.4 years. All 5 patients treated with supportive treatment alone died of infection or progression at the median age of 13.5 years, except for one with short follow-up duration. Acute leukemia developed in 2 patients at 15.4 and 18.1 years of age. Among 6 patients who are still alive, 3 had short stature and 1 developed insulin-dependent diabetes mellitus. CONCLUSION: We provide information on the long-term outcomes of FA patients in Korea. A nation-wide FA registry that includes information of the genotypes of Korean patients is required to further characterize ethnic differences and provide the best standard of care for FA patients.

Gastroesophageal reflux disease (GERD) is thought to be caused by an incompetent lower esophageal sphincter, either because of a chronic hypotonia or an increased frequency of transient lower esophageal sphincter relaxation. Thus, it seems paradoxical under nutcracker esophagus to consider gastroesophageal reflux as a possible diagnosis, particularly in the patient presenting with chest pain. Current therapy in nutcracker esophagus is aimed at reducing the high amplitude peristaltic contractions characteristic of this disorder. Treatment directed at reducing contraction can decrease lower esophageal sphincter pressure and may exacerbate gastroesophageal reflux. It is not easy to treat a case of nutcracker esophagus associated with GERD. We report a 38-year-old male with nutcracker esophagus associated with GERD who lost the diagnostic features of nutcracker esophagus after 6 week of antireflux therapy.

PURPOSE: To evaluate the sedative effect of add-on chlorpheniramine in children with neurologic diseases failed to sedate with chloral hydrate and midazolam. METHODS: Thirty three patients who had not been successfully sedated with oral chloral hydrate and intravenous midazolam for diagnostic examinations were attempted for sedation with intravenous chlorpheniramine at Chonnam National University Hospital from September 2007 to September 2012. The sedative effects were compared on the aspects of age, sex, body weight, dosage of drug and underlying neurologic conditions with the retrospective review of medical records. RESULTS: Among 33 patients, 26(78.7%) were successfully sedated and 7(24.2%) failed to sedate. The success rates were different by age and were decreased with age: 100%(0-4y), 84.6%(5-9y), 50%(10-14y). The effectiveness of chlorpheniramine was not significantly different in terms of ages, sex, body weight, dosage of drug and the underlying neurologic conditions-developmental delay, seizures or organic brain lesions. Children with ADHD(attention-deficit hyperactivity disorder), however, showed a significantly lower success rate than the non-ADHD patient group (28.5%, P=0.002). No serious side effects were reported except for one case with transient perioral cyanosis. CONCLUSION: Chlorpheniramine appeared highly effective in children with neurologic diseases who had not been sedated with chloral hydrate and midazolam. The efficacy seemed to be higher in the younger age groups and lower in children with ADHD.

PURPOSE: To study the effect of recombinant human epidermal growth factor (rhEGF) on oral mucositis induced by cisplatin and radiotherapy in a mouse model. MATERIALS AND METHODS: Twenty-four ICR mice were divided into three groups? the normal control group, the no rhEGF group (treatment with cisplatin and radiation) and the rhEGF group (treatment with cisplatin, radiation and rhEGF). A model of mucositis induced by cisplatin and radiotherapy was established by injecting mice with cisplatin (10 mg/kg) on day 1 and with radiation exposure (5 Gy/day) to the head and neck on days 1~5. rhEGF was administered subcutaneously on days -1 to 0 (1 mg/kg/day) and on days 3 to 5 (1 mg/kg/day). Evaluation included body weight, oral intake, and histology. RESULTS: For the comparison of the change of body weight between the rhEGF group and the no rhEGF group, a statistically significant difference was observed in the rhEGF group for the 5 days after day 3 of the experiment. The rhEGF group and no rhEGF group had reduced food intake until day 5 of the experiment, and then the mice demonstrated increased food intake after day 13 of the of experiment. When the histological examination was conducted on day 7 after treatment with cisplatin and radiation, the rhEGF group showed a focal cellular reaction in the epidermal layer of the mucosa, while the no rhEGF group did not show inflammation of the oral mucosa. CONCLUSION: These findings suggest that rhEGF has a potential to reduce the oral mucositis burden in mice after treatment with cisplatin and radiation. The optimal dose, number and timing of the administration of rhEGF require further investigation.
